DAVID Gr. HASKINS, OF CAMBRIDGE, MASSACHUSETTS.

Specification forming part of Letters Patent No. 53,820, dated April 10,1866.

To all whom it may concern Beitknown th atI,DAVID GREENE HASKINS, ofCambridge, in the county of Middlesex and State of Massachusetts, haveinvented a new and improved method of heating houses and apartments bythe flame of gas or that Of any oils or fluid which can be used for thepurpose by means of an apparatus hereinafter described; and 1 do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 represents a longitudinalsection of my apparatus, showing,in detail, several of the devices Idesign to make use of in carrying out my invention. Fig. 2 represents a.plan view of the same, and Figs. 3 and 4 are transverse sections of thesame, taken at the lines marked a: 00 and y 3 in Fig. 1.-

Similar letters indicate like parts in the several figures.

The object of my invention is to warm one or more apartments by airheated by the flame of gas or that of oils or other fluids which can beused for the purpose by means of pipes or conducting-tubes provided withregisters introduced into the floors or walls of the apartmen ts. Acurrent of air is caused to pass over or through a series of radiatingmaterial so arranged as to absorb, conduct, and radiate the heat whichmay be imparted to the said material from the burning gases, 850.

The smoke and vitiated air from the burning gases, 820., are conductedoff in aseparate pipe or flue to the chimney or other place of exit.

In the drawings, A represents an outer casing, which may be of acylindrical or other form and made of tin, galvanized iron, or othersuitable non-conductin g material. Within this casing is a smallercompartment or chamber, B, extending nearly the whole length of thecasing, and made of cast or sheet iron or other good conducting orradiating material. The chamber B is made much smaller than the easingA, so as to leave a considerable space befrom oils or other fluid, theflame passing into the chamber B.

At the rear end of the chamber B is a pipe, I, which passes into andextends to near the upper part of a drum, K, of any convenient ordesirable form, and at the lower part of the drum is a pipe forconveying the products of combustion to the chimney.

The front part of the chamber B is provided I with a door, M, forconvenience of access to theinterior of the said chamber when necessary,but is designed to be kept closed when the apparatus is in operation.

Within the chamber B may be arranged transversely one or more sheets orpieces of wire-netting, as shown at 1), Figs. 1 and 3; or a series ofmetal plates extending partially across the chamber may be used, thesaid plates being attached alternately to the upper and lower sides ofthe chamber B, for the purpose of retarding the passage of the productsof combustion and aiding in the radiation of heat.

In the space between the chamber B and outer casin g, A, is arranged aseries of devices, presently to be explained, in such a manner and ofsuch material as to absorb, conduct, and radiate the heat derived fromthe burning gases in the chamber B. The front end of the outer casing,A,is left open, and maybe made to communicate with the outer air, or theair may be supplied from the cellar or apartment in which the apparatusis located.

I11 the drawings are represented a variety of devices designed to beused in the air-heating space before referred to; but it is notnecessary that all should be used in one apparatus at the same time. Thespace may be filled or provided with all of one design, or two or moremay be used in combination.

D D represent hollow pipes passing transversely across the space betweenthe casingA and chamber B, arranged concentrically with the outercasing, and placed at a greater or less distance from the same. The endsof the said pipes communicate with the inner part of the casing B, so asto permit the passage of the heated gases through the pipes.

F F are solid cylindrical rods attached at each end to the casin g, andarranged similarly to the hollow pipes D.

E E represent sheets or pieces of wire-netting placed transverselyacross the air-heating space between the pipes D and F, with which theyare in contact, and, becoming rapidly heated, serve to impart additionalheat to the air in its passage through the casing.

G G represent also sheets or pieces of wirenetting arranged within theair-heatin g space, and projecting upward at intervals from the upperpart of the chamber B, to which they may be secured in any suitablemanner.

Instead of wire-netting any other reticulated conducting material may beused.

H H are hollow pipes or tubes, which may be coiled or arranged in azigzag position, communicating at one end with the inner chamber, B, andat the other end with the discharge-pipe at the rear of the saidchamber.

By thus arranging the above-described ra diating devices within theair-heating space a high degree of heat will be imparted to the same, sothat the air passing over and between them will become suffieientl yheated to warm apartments to which it may be conducted by 'pipes leadingfrom the heating apparatus.

Actual experiment with a full-sized apparatus has demonstrated that witha comparatively moderate supply of gas a high degree of heat may beobtained.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. The application, substantially after the manner herein described, ofthe flame of any gas, or of any oil or fluid, to the heating of acurrent of air which may be introduced from without into rooms,apartments, or buildings.

2. The combination, with an outer casing, A, and an inner chamber, B, ofheat retainin g and radiating devices, substantially as and for thepurpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DAVID GREENE HASKINS.
